l Mohall, inthe county of Ward and State, of

North Dakota, have invented a'new and useful Coupler foi` Traction-Engines, of which the` follow-ing 1s a s ecilication.

This inventio'nre ates lgenerally to eoiip v1ers and specifically to devices of the above.

mentioned'class which arepeculiarly adapted for use upon traction engines.

The objects of the invention are, the pro'- vision in a merchantable form, of a device of the above-mentioned lclassI which shall be inexpensive to manufacture, facile in operation and devoid of complicated parts; the

provision of detentl and releasing mechanisms of a novel form; and nally, the positioning of the com nent parts vto form a eonpact and presen blecoi'pler.

ith these objetsin v'iev'v, together with others which a perusal of this specification will reveal to those skilled inthe art, the invention consists in the novel construction and arrangement of parts hereinafter described, delineated in the accompanying drawings and particularly pointed out in the appended claims, it being understood that various changesin the form, proportions, size and minor details of the structure may be made without departing from the" spirit or sacrificing any' of the advantages of the invention.

Similar numerals of reference 'are eins ployed to indicate corresponding `arts throughout the several figures of the law'- in s. l

n the accom vanying drawings; Figure 1 is a top plan of my invention set toreceive a conventional couplingpin 19; Fig. 2 is a top plan upon an enlargedscale, the cover 2 .being removed and the' coupling mechanism shown in an openpo'sition; Figr is a side elevation uponI a Ireduced scale; Fig. 4 is a top plan upon the saine scaleas Fi 2, the cover 2 being removed and the coup ing mechanism shown in a closed positioni I,

In carrying out my invention, I provide a housin 1, comprising and a ase-plate 3. Il`he 1housing 1 is provided with an interior chamber', open at its sides and terminated at its .rear -by a artition 4. The forward end of the chain er is terminated by a straight vertical face 5, disosed at an acute -angle to -the draft-line -'-X, the said straight vertical face 5 bepreferably a cover 2` comme me @marion-meme.'

-ing formed the rear ends of the headblocks 6 and 7, which, if desired, may be fashioned integral with the baseplate 3. The faces 5 vform a'shoulder, against which bears with a Sliding contactvthe detent 12.

V The housing' liis provided with a vertilcally` incised pin-slot, flaring at its forward end to forni the jaws 9 and 10. As the pin-slotl 8 extends rearward beyond the flaring portion, its walls proceed substantially parallel, to a point to the rear of the being'cdisposed at an angle to the draft line X- cros'sing the straight vertical face 5 substantially in the draft line X-X. The pin slot 8 terminates rearwardly inthe ace 5,.

Within the 'chantier is iinted the detent i2, havin fatwa-a1y edge is sliding contact. with fc ace; The detest 121s 'extendingrearward and laterally from the forward face of they detent 12, the lateral inclination. of the slot13 being in a direction contrary to that assumed by the terminal 11 of the iii-slot. From one end of the rear ledge o the datent` 12, projects rearwardly the shoulder 14, adapted to engage successively the notches 1 5 and 16 in the lever 17. which is ivotaiy mounted at i8 within the Vhousing its movable end projecting without the; housin C1. The slot 13 is so disposed in the datent -2 that, when the shoulder 14 engages the notch 16,7the mouth of theslot 13 will register with the pin-slot 8, as shown in Fig. 2, and when the shoulder 14 engages the notch '15, the mouth of the slot 13 Will havepassed the pin-slot 8 closing the said pinslot, as shown in Fig. 4. When the dethe terminal o the s'lot 13 will register i with the end 11 of the pin-slot 8 to forma socket within'vvhich the coupling pin 1 9 will -be retained. -The' lever 17 is held in engagement with the datent iaby thesprm 20; retained at one end by' the pintle 2 1 an fulcrumed upon the pintle 22. Conveniently disposed bolts 23 may be provided to fasten the cover 2 to the base dplate 3,- the apertures in che bas plate 3 apted to'recive the bolts 23bcing designated by the numeral 24 in Figs. 2 and 4. My invention may be attached to the draw-bar v27 of the machine of which it is a part, by any suitable method.

fortionv 11, approximately parallel to t'he I have shown, as adapted'to this end, the' straight vertical face 5, the parallel walls provided with a vertically ieis'ed slot 13,

tent 121is in the ositionlast above described,

apertures 25, through which connecting bolts 26 may be passed. l

'Ifo the movable end of the lever 17 may be attached means whereby the lever 17 may be operated from the cab of the engine, or from any other point from which it is 4desired to control'the device.

Let it be supposed that the detent 12 0cciipies the position shown in Figs. 1 and 'When the pin 19 moves between the jaws 9 and l0, it will be deflected into the slot 8, striking the detent 12 and sliding it into the position shown in Fig. 4 where it will be held by the engagement of the shoulderv 1,4'

with the notch 15, the slot 8, being closed as shown in Fig. 4.y When it is desired to break the coupling, the lever 17 is moved rearward and the shoulder'l4 freed from the notch 15,. r[he pin 19 will follow `the lportion 1'1 of the pin-slot, which said 'portion extends substantiallyparallel 'to the face 5. The pull upon1 the` pin 19 in the direction of the draft-line XfX, will have a component in the line of the straight vertical face 5fr and-this component will cause the detent 12 to slide into the position shown in Figs. 1 and 2,` freeing the pinl19 and permitting itto ass out between the jaws 9-and 10. Shoul the detent 12 assume tlie position shown in Fi .34 when the coupling gin 19y is not en age by the detent 12,'the `etent l2 may e moved manually to the position shown in Figs. 1 and 2, when the device will be ready to receive and 'retain the pin 19. When the detent 12 occupies the position shown in Figs. 1 and 2, the engageto the lateral bend ofthe pin s ment of the shoulder 14'with the notch 16 will prevent the detent 12 from moving into an .extreme and inoperative position.

Having thus described my invention, my claims are as follows: 1. A coupler comprisin a housing having a vertically incised pin s ot terminating in a lateral bend; headv blocks mounted in the end of the housing upon op osite sides of the 'pin slot, the ,said head blo ks terminating rearwardly in strai ht vertical, alined faces disposed atan ang e, laterally, to the draft line of the coupler; in slidin contact with the alined faces ofthe headb ocks, a detent having an excision from one of its edges, the said excision disposedlaterally at an angle ot, the mouth of the said excision being adapted to register with the pin slot, and the terminal of the said excision being adapted to register with the lateral bend of the pin slot, alternately, in successive ositions ofthe detent; means for limiting t e movement of the detent.

opposite sides of the pin slot, the said head blocks terminating rearwardly in straight, vertical, alined faces disposed at an angle, laterally, to the draft line of the coupler; in sliding contact with the alined faces of the head blocks, a detent adapted to intercept a portion of the pin slot; a shoulder projecting from the detent; mounted in the housing, a lever having notches adapted to engage the shoulder in successive positions of the detent; means for holding the-lever yieldingly against the detent.

3. In a device of the class described, a housing having a vertically incised pin-slot terminating in a lateral bend; slidably mounted in the housing, a detent having an excision from one of its edges, the said excision disposed lateral-ly at an angle to the lateral bend of thepin-slot, the mouth of the said excision adapted to register with the pin-slot, and the terminal of the said excision adapted to register with the lateral bend of the pin-slot, alternately, in successive ositions of the detent; means for limiting t e movement of the detent.

4. A coupler comprising a housing having a vertically incised pin-slot; head-blocks mounted in the end of the housin upon o posite sides ofthe pin-slot, the said headb ocks terminating rearwardly in straight, vertical, alined'faces disposed at an angle, horizontally, to the draft-line of the coupler; in sliding contact with the alined faces of the head-blocks, a detent adapted to intercept a portion of the pin-slot; means for limiting the movement of the detent.

5. ln a c'oupler, a housing having a vertically incised in-slot terminating in a lateral bend; head b ocks mounted in the end of the housing upon opposite sides of the pin-slot, the said head blocks terminating rearwardly in straight vertical alined faces disposed at an angle laterally to the draft line of the coupler, and parallel to the terminal bend of the pin slot; in sliding contact with the alined faces of the head-blocks, a detent adapted to interceptthe lateral bend of the pin slot; means for limiting the movement of the detent.

In testimony that I claim the foregoing as m own,'1. 'have hereto aiixed my signature 1n the presence of two witnesses.
